If you have an Open event macro for your workbook and this macro has code to activate a worksheet, the macro will run, but the worksheet may not be activated.


Your Open event macro may not activate a worksheet if both of the following are true:

  • You have a custom function, either in the workbook with the Open event macro, or another workbook in memory. -and-

  • Your custom function uses the Volatile method.

To work around this problem, use either of the following methods:

  • Remove the line of code containing the Volatile method from your custom function. -or-

  • Use an Auto_Open macro instead of an Open event macro for the workbook.

For example, if your Open event macro is as follows:

   Private Sub Workbook_Open()
   End Sub

use the following macro code (on a general module) instead:

   Sub Auto_Open()
   End Sub


Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem no longer occurs in Microsoft Excel 2000.
